November 9 to November 16, 2019 is predicted to be the peak time in Eureka Springs, AR to observe the changing leaves.
Some consider it to be the most incredible time of the year. Gorgeous colors vibrantly encoring the end of summer as the trees put themselves to bed for the long sleep of winter. Eureka Springs, Arkansas floods with thousands of annual visitors all hoping to achieve a breathtaking view of the beautiful renaissance of nature.
Why do leaves fall?
The beauty of nature is sometimes found in the profound ‘intelligence’ it exudes. Perennials, which includes trees, must protect themselves in order to get through the harsh, freezing temperatures of winter. If trees did not shed their leaves, their soft vegetation would certainly freeze during winter time, damaging and, no doubt, killing the tree.
In order to cope with the grueling winter temperatures, trees slowly close off the veins that carry water and nutrients to and from the leaves with a layer of new cells that form at the base of the leaf stem, protecting the limbs and body of the tree. Once the process of new cell creation is complete, water and nutrients no longer flow to and from the leaf - this enables the leaf to die and weaken at the stem, eventually falling gracefully to the ground.
What happens to the fallen leaves?
Earth, among other things, is fantastic at recycling. Whether through the water cycle, or the slow process of decomposing plants and trees back in to rich soil, the Earth wastes very little.
When leaves fall to the ground, they begin to break down and eventually create a rich humus on the forest floor that absorbs dew and rainfall. This nutrient rich ‘sponge’ acts as a continual source of nutrients and water for trees and plants, helping to promote life and plant health in the next spring season.
It is not difficult to conclude that while the falling of the leaves protects the trees through winter, it’s likely that trees would not survive as well without the rich layer of dead leaves through the warm spring and summer months. In this way, trees' natural cycle provides health and sustainability for itself year after year.
